Authenticate every device for enhanced security

Set up individual identities and credentials for each of your connected devices to help retain the confidentiality of both cloud-to-device and device-to-cloud messages. Selectively revoke access rights for specific devices as needed.

Extend the power of the cloud to your edge devices

Easily create and deploy IoT Edge modules to transmit code and services between the cloud and the edge. Distribute intelligence—including AI and other advanced analytics—across a range of devices. All while reducing your IoT application costs, easing development efforts, and running devices offline or with intermittent connectivity.

"By analyzing sensor data from a connected car in Azure, drivers can see alerts about engine issues and metrics about gas consumption and driving performance, such as idle time. They can also configure their own recipe for rating their driving style and then drill down for details."

Frequently asked questions about Azure IoT Hub

IoT Hub Basic is an ideal place to start your IoT deployment if you don’t need bi-directional communication but still with foundational IoT security with per-device authentication, highly scalable device support, and a seamless upgrade path to IoT Hub Standard. Standard enables device management and Azure IoT Edge support. Event Hub is designed for big data scenarios, such as website data ingestion. See a detailed comparison.

Each Azure subscription has default quota limits to prevent service abuse. These could impact the scope of your IoT solution. The current limit is 50 IoT hubs per Azure subscription. To request quota increases, please contact support. Get more details.

Azure IoT Hub and IoT Hub device SDKs support the following protocols for connecting devices.

HTTPS

AMQP

AMQP over WebSockets

MQTT

MQTT over WebSockets

If your application can’t use one of the supported protocols, extend IoT Hub to support custom protocols by doing the following.

Use Azure IoT Edge to create a field gateway to perform protocol translation on the edge.

IoT Hub scales to billions of connected devices and billions of events per second, simultaneously, to support your IoT workloads. Choose the service tier that best fits your scalability needs. Learn more on the pricing page.
